    if (mBtnLeft) {
        result |= AMOTION_EVENT_BUTTON_PRIMARY;
    }

    if (mBtnRight) {

        //修改这里即可

        //result |= AMOTION_EVENT_BUTTON_SECONDARY;
result |= AMOTION_EVENT_BUTTON_BACK;
    }
    if (mBtnMiddle) {
        result |= AMOTION_EVENT_BUTTON_TERTIARY;

    if (mBtnBack || mBtnSide) {
        result |= AMOTION_EVENT_BUTTON_BACK;
